Product Description

The PowerAid Throttle Body Spacer was developed to enhance your vehicle’s off-idle to mid-range performance and efficiency. The unique “Helix Bore” design of the PowerAid creates a spinning action of the incoming air. As air passes through your throttle body, this helical effect causes the air molecules to organize and maintain high velocity. The organization and high velocity of the air is extremely beneficial because it helps to provide a superior atomized mixture of fuel and air all the way into the combustion chamber. The benefits you will see are tremendous torque gains between 800 to 2500 RPM, and potential increases in your fuel economy, depending on driving conditions.

PowerAid Throttle Body Spacers are manufactured from the highest quality Aircraft Grade Billet 6061-T6 Aluminum. Each PowerAid is specifically designed for your application. Our kits always include the necessary gaskets, hardware, and precision brackets to maintain proper geometry with the factory components. The PowerAid Spacer can be installed in less than an hour using common hand tools with no drilling or cutting required.



Each AIRAID product line is the result of exhaustive research and development. Their in-house engineering team consists of both mechanical and industrial design engineers using the latest 3-D CAD modeling equipment to produce advanced designs that make more power right out of the box. A portable 3-D scanner and rapid prototyping machine allows AIRAID to test new products on their in-house Superflow flow bench and verify the unmatched fit, finish, and style that AIRAID customers demand. All products are then tested on their all-wheel-drive Mustang chassis dynamometer to produce real-world performance numbers.

PowerAid Throttle Body Spacers are proudly Made in the USA, with the same level of quality control, fit, and finish you would expect from the rest of AIRAID’s product line. Just like our filters, PowerAid products carry our Lifetime “No Hassle” Warranty!
